World’s first all-electric ocean-going vessel to enter service in 2027
Corvus Energy, a leading provider of zero-emission solutions for the shipping and marine industries, has announced that it will supply a large-scale battery system for the world’s first all-electric vessel.
The vessel, an electric commissioning service vessel (eCSOV), will be built by Spanish shipyard Armon for UK-based shipowner Bibby Marine Ltd. It is expected to enter service in 2027, supporting the operation and maintenance of offshore wind farms.
Corvus Energy will supply the Blue Whale Battery Energy Storage System (BESS), which will provide approximately 25 MWh of power, making it the largest lithium iron phosphate (LFP) battery system ever used on an offshore project.
A spokesperson for Corvus Energy said the offshore industry has long been committed to building all-electric vessels. The eCSOV will be the first naval vessel capable of operating entirely on battery power all day, setting a new standard for future naval vessels.
The vessel will also feature a dual-fuel methanol engine that works in conjunction with a battery system to reduce carbon emissions and improve energy efficiency while maintaining reliability and high performance.
Corvus Energy works with shipowners, designers and integrators to optimize the vessel’s electrical system. Unlike conventional hybrid vessels, this hybrid electric vehicle will use its large battery pack as the primary source of power, with the engine used only for charging at an optimized constant load.
This approach achieves maximum efficiency, extends battery life and significantly reduces emissions. The vessel will also feature an innovative DC grid architecture, which will reduce energy losses and ensure smooth distribution of power.
In addition, the vessel will offer offshore charging capabilities, allowing the batteries to be charged while maintaining dynamic positioning (DP) to maintain position. This will be the first time such a system has been implemented on a Service Operation Vessel (SOV).
A representative from Bibby Marine said the company was pleased to work with Corvus Energy on this innovative eCSOV project.
The company selected Corvus Energy because of its extensive experience in handling complex vessel projects. LFP battery technology was chosen due to its safety, long life and reliability, which is well suited to the operational needs of the eCSOV.
The battery system is scheduled to be delivered to the shipyard in 2026 and the vessel is expected to start operations in 2027.
Corvus Energy is a leading global supplier of Energy Storage Systems (ESS) for marine, coastal and port applications. The company offers modular lithium-ion battery systems and hydrogen PEM fuel cell systems that can be used to support various types of vessels.
With experience in more than 1,200 projects, Corvus Energy powers more than 50% of the world’s zero-emission vessels.
